CROSS-REFERENCE TO RELATED APPLICATION

The present application claims priority to, and the benefit of, U.S. Provisional Application No. 63/037,125, which was filed on Apr. 15, 2020 and is incorporated herein by reference in its entirety.

BACKGROUND

The present invention generally relates to an airflow device, and more specifically to a tool configured to provide an influx of oxygen to a fire in a fireplace adequate to support combustion. Accordingly, the present specification makes specific reference thereto. However, it is to be appreciated that aspects of the present invention are also equally amenable to other like applications, devices and methods of manufacture.

Starting and maintaining a fireplace fire can be intimidating, difficult, and time consuming. Standard wood burning fireplaces may be unable to kindle the flame enough to maintain a desired temperature to support combustion. When wood is split not small enough or there is not enough kindling, it can be difficult to keep the fire going. Heat may be lacking, and people may be forced to constantly maintain the fire.

Wood burning fireplaces are popular for several reasons. There is an aesthetic ambiance created from a fireplace fire. Homeowners can also use the fires as a source of heat to supplement other heating sources. People often cook over fireplace fires. These fires can also be a source of light and heat in the event of a power outage. However, there are disadvantages in that fireplace fires require a lot of attention to achieve and maintain an efficiently burning fire. Additionally, incomplete combustion leads to excess smoke.

All fires require three elements to maintain the chemical reaction of combustion: heat, fuel, and an oxidizer. Fire is simply the result of applying enough heat to a fuel source when there is sufficient oxygen. As the atoms of the fuel heat up, they vaporize into volatile gasses. The gasses react with the available oxygen in the atmosphere. The chemical reaction eventually produces enough heat to keep driving the reaction. As long as there is enough fuel and oxygen remaining, the reaction then becomes self-sustaining. Heat energy is released in the form of light. For a fireplace fire, wood is the typical fuel and household air provides the oxygen.

One common problem with home fireplace fires is that they can be difficult to start or maintain once started. The fire draws air from the room at a regular rate, but that is not always enough to start or maintain the fire sufficiently. The fireplace bellows is a tool designed to introduce both fresh air and a steady flow of air to the space around a fire. That air current both removes the carbon dioxide that the fire itself produced and introduces more oxygen-rich air to the mix, keeping your flame burning higher and hotter.

Operating a traditional fireplace bellows is relatively simple. Since the fire requires oxygen, the more oxygen supplied, generally the more complete the combustion. Bellows work by focusing a concentrated stream of air through an outlet or nozzle allowing oxygen to be delivered to the base of the fire. This additional oxygen accelerates the chemical reaction of combustion leading to fire growth. However, too much air can extinguish the fire, especially if the chemical reaction is at a vulnerable level.

Bellows can also create problems if not used safely. The tips can easily heat up causing a burn hazard and over squeezing can blow embers out of the firebox creating a fire hazard. One problem with electric bellows is that they typically produce hot air, similar to a hair dryer, causing the unit to heat up to the point it may burn people. Another problem is the lack of adjustable speeds. While one speed may be useful to maintain a full burning fire, it may not be sufficient to start one or maintain one with a low fuel load.

In this manner, the improved airflow device of the present invention accomplishes all of the forgoing objectives, thereby providing an easy solution to keep a woodburning fire in a fireplace going without the need for constant human intervention. A primary feature of the present invention is a fireplace improvement tool facilitating better and more effective wood burning. The invention increases the heat output of the fire thereby reducing the amount of maintenance required to keep the fire burning effectively. Finally, the improved airflow device of the present invention is capable of improving airflow to a fire in a consistent manner.
